Refinance Loan Calculator
Estimate your savings by refinancing your mortgage
Calculating your refinance savings…
When interest rates drop or your financial situation improves, refinancing your mortgage can be one of the smartest financial moves you make. The Refinance Loan Calculator is a free, easy-to-use online tool that helps homeowners quickly determine whether refinancing their current mortgage makes financial sense. By entering key details like your current loan balance, interest rate, and new loan terms, you can instantly see your potential monthly savings, break-even time, and total lifetime savings.
This article explains exactly how to use the tool, provides a real-world example, and offers practical tips to help you make the most informed refinancing decision possible.
What Is the Refinance Loan Calculator?
The Refinance Loan Calculator is an online tool designed to estimate how much you could save by refinancing your existing mortgage. Refinancing involves replacing your current home loan with a new one—typically at a lower interest rate or over a different term length.
This tool helps you:
- Calculate new monthly payments
- Estimate monthly savings
- Determine your break-even point (how long before you recoup refinancing costs)
- Project total savings over the life of the loan
With this data, you can make a confident, informed decision about whether refinancing is financially worthwhile.

Practical Example: Refinancing in Action
Let’s walk through a realistic scenario:
- Current loan amount: $250,000
- Current interest rate: 5%
- Years remaining: 25
- New interest rate: 4%
- New term: 30 years
- Closing costs: $4,000
After entering these numbers and clicking Calculate, the Refinance Loan Calculator might show results like:
- Current Monthly Payment: $1,462.50
- New Monthly Payment: $1,193.54
- Monthly Savings: $268.96
- Break-Even Time: 15 months
- Total Savings Over Term: $80,688
This means that within just over a year, the money you save each month will outweigh the upfront closing costs—and you’ll save more than $80,000 over the full loan term.
For many homeowners, this data confirms whether refinancing is worth the effort.
